Thin Metal

This is the simplest way to make a metallic effect. It relies on the fact that when you see metal in real life, it’s usually got lots of highlights and shadows, especially shinier, chromier type metals. So by using two copies of the same gradient at different angles you can make this effect happen really easily and give your text a metallic effect.
It’s best on a thin typeface because otherwise the interior of the text looks dull and flat (unless of course we added more styling, but then it wouldn’t be super quick!)

So first of all I decided to make my text ‘stand up’ in this example. So just create a layer below your text and draw tiny circles of black below the points of each letter. Then blur them by going to Filters > Blur > Gaussian Blur and set it to about 2px. Then hit Ctrl+T and squash them vertically. Finally set them to about 30% Opacity so they are nice and faded out.
For letters like the a and e where there is a larger area of the letter touching the ‘floor’, you can use the transform tool to stretch the circle our horizontally.
Finally I duplicated one of my circle shadows and stretched it waay out so that it went underneath the whole bit of text to make the overall shadow.
Experiment and you should be able to create some neat little pools of shadow under the letters.

Now the actual text is just a combination of a Gradient Overlay and a 1px Stroke that uses the same gradient. The gradient we use (and it’s the same as in the Double Type effect above) is a metallic gradient that comes with Photoshop. You can add this to your gradients palette, using that little right arrow shown in the Gradient Editor below, then choose Metals and you should see it appear.
The key here is to make sure the Angle on the overlay and the stroke is different. This is what creates the highlights on the text that you can see in the close up screenshot above.
I also set the main overlay to just 14% Opacity over the top of some grey text so that it was a little faded out, but that’s optional.
